If you’re limited to those powders, don’t waste your time.
Your .264 will perform just like your 6.5X55

The .264 demands the slowest burning powders.

H1000 ?
Magpro ?

US869 is what I settled on - and it's right there at the bottom of the burn rate chart.

80 gr with push a 130 gr TGK to 3,300 fps
77 gr gets to 3,100 fps with 139-143 gr bullets

US-869 works well. I've also used WC-872. Temp sensitive and dirty but good velocity

I run 140gr npt's to an easy 2800 fps in my hunting weight 6.5x55 Swede with RL-22 and 25" barrel, great combo, 160gr Woodleigh's run 3000 fps with RL-33 in a 26" barreled pre-64 264 WM, that said, and you may want to do the same, i went to midwayusa and ordered several boxes of 140gr Speer Grand Slams on the cheap, you can get them there or directly from Speer's website, thought was if Woodleigh never gets back up and going or i'm long ran out of their 160's, i'll happliy hunt all manner of light big game with those 140 Grand Slams at 3000 fps and live happily ever after.

We all have specialized cartridge/bullet/scoped rifle setups for large, small, dangerous, near or far, but imho a point and shoot rig to 400 long yards with 140's at 3K will get a lot done for me in a general game hunting rifle, good luck, it's a great and fun classic cartridge.

You've got that one dialed in and ready Buddy, i'd just sit the 140gr SGS on top of the same charge of RL-33 as the 160 Woodies and see where they landed, i dont think they'd be as tough as your 140gr AB's so i wouldn't be looking for 3200 with them.

I used to use 7828ssc in mine with success, before I "discovered" RL-33.
I've only ever shot 130 AB's out of mine.
Taken plenty of big deer with them, never recovered a bullet.
No hesitation taking a elk with that combination either.
One of my easiest rifles to load for, a pre64 Westerner with original 26" SS barrel.

When you decide to own a .264 Winchester Magnum, you’ve just signed up to be your own ballistician.

Until recently, data was not available for the newer, slow-burning powders.

And wasn't for years. There wasn't any data for Ramshot Magnum when I started using it in the .264 in 2004....

Did you use 7 Rem Data to start? Just wondering. That has always been why I’ve liked have QL. Maybe not perfect but I could always figure out a place to start.

It was shortly before before QL appeared, if I remember correctly.

Used a variety of techniques, including measuring case-head expansion (which I'd already started to distrust, but can provide approximate info if used correctly). But the major "formula" was the one I worked out by crunching numbers from various pressure-tested sources: Any increase or decrease in bore area results in about 1/4 as much potential increase/decrease in velocity at the SAME pressure, using the same bullet weights. Used this by comparing the .264 with the extremely common data for the 7mm Remington Magnum.

Also looked at what data was available with other powders, and between the two comparisons came up with approximately how much velocity the .264 should be capable of with various bullet weights. Had already used this technique for coming up with .300 WSM data for an article in HANDLOADER, before any pressure-tested data appeared--and when tested data appeared my powder charges only varied by at most a grain of powder, and more often within a half-grain.

This includes the presently published data for Ramshot Magnum in the .264.

I once bought a used push feed M70 with a 24" barrel. It was a solid 1-1/2 to 2" rifle with everything I ever shot through it. Just for fun one day I tried the now discontinued Sierra 85 gr HP working up to a case full of H4831. Bugholes @ 3600+ fps for 3 or 4 shots until the barrel got hot. Spread over time for cooling, 5 or 10 shots would go into 1/4" or so. It was fun for a while, but not terribly useful except for the odd groundhog inside 300 yds. The Swift was a better killer to longer ranges burning about 1/2 the powder. One day someone had to have that .264 more than I wanted to keep it, so it went DTFR. Never really had the urge to buy another except for a limited run Ruger 77 tanger that remained NIB in the safe for 20 years. Someone just had to own that one too after it became somewhat rare & collectible.


The old Dutchman once told me that fate watches over fools, drunks, & handloaders. Since getting on the internet, I'm pretty sure he was right.

I bought one of these about 4 years ago and it's been a nightmare trying to find an accurate load. Half a dozen different powders and bullets and the only combo which I could get MOA results was with a 140 VLD and Retumbo.

All other loads with Nosier, Sierra and Hornady bullets were 1-1/2 MOA at best with some 3-4 MOA.

Barrel has a lot of tooling marks and needs to be replaced but just haven't done it yet. Most frustrating rifle I can remember in a long time.

But it is pretty.... crazy

Before you scrap that barrel, try the Tubbs bullets on it. It’ll be worth the 35 bucks to know if the barrel is shot or can be uniformed and smoothed out. They have saved a few barrels just like what you mentioned.

Love the .264. Old school cool that was handicapped by powders and twists. This one is a Howa 1500 with a Preferred barrels tube with a 7 1/2 twist. Puts the 147 ELDM into the group shown at 200 yds. It put this cow elk down with zero fanfare, in fact it was a little anticlimactic. A one and done deal.
